To all whom" it may concern:

Be it known that I, DAVID CAIRD, of London, England, have invented certain new and useful Improvements in Metal Barrels and other Like Vessels, (which has been in part patented by me in Great Britain-by Patent an nular in ward] y extending recess in its outer surface and an annular lateral flange beyond said recess, and abutting against and connected to the like flange of the other part, said flanges being of less projection than the depth of said recesses, whereby the joint be: tweensaid parts 'is within their outer surfaces, and in certain other details of construction wh'ch will be hereinafter fully set forth.

In thd accompanying drawings,Figure 1 is-a vertical section of a metalbarrel or vessel made in accordance with my invention in halves which are connected together in the manner that I preferably adopt. Fig.2 shows in longitudinal section a portion of each of the half barrels with their flanges buttingagai'nst each other and ready to be connected together so as to form a liquid tight joint. Fig. 3 shows the same parts with the flange of the one half fohded upon the flange of the other half,as in. the intermediate position of formingtliejoint or connection between them.

Fig. tThows the same parts with the flange ,or the ohe half doubled over behind the flange 0 the other half as when the joint or "conuecti n between them is complete. Figs. 5, 6 and 7 respectively illustrate modifications of the manner of forming the joint or represents a modification in which the barrel is made in four parts or sections which are connected together inthe manner'illustrated by Figs. 1 to 4. Figs, 1 and Sare drawn to a 'smaller scale than the other figures.

' -In carrying out my invention I stamp or draw each half or part barrel'out of a circular sheet or blank of metal. For the smaller sizes this can be effected by a series of stamping or drawing operations including the formation of a hung hole and of corrugations when required in the head or end; but for larger sizes it may tion by spinning after the stamping or drawing operations. The half barrels having first been trimmed 1 next according to the preferred manner of manufacture form an outturned flange around the edge of each half barrel, the flange on the one half barrel being wider than that on the other half barrel for the purpose about to be explained, and I also form a groove or recess around the periphery of each half barrel next its flange. Having thus made the two half barrels I place them together flangeto flange eitherwith or without a suitable packing and I then double or fold the flange of the wider flanged half over the flange of the other half .and well press the two flanges together. The result is aliquid tight-joint; if desired the joint thus made can be brazed or soldered. The flnishedjoint should be somewhat below or under the bilge or belly of the barrel. j

a a in Fig. 1 are the two barrel heads or ends and b b are the two half bodies, each half body being formed in a piece with the corresponding-head a by stamping or drawing as hereinbefore described.

c and c, Fig. 2, represent the flanges formed respectively on the two half bodies,and d d are the grooves-or recesses formed around the. half barrels next the flanges c c. Thedepth of these 'grooves relatively to the width of the flanges is such that the finished joint is somewhat under the bilge of the barrel (see Fig. 4

The half barrels b I) having been placed flange to flange as seen in Fig. 2 the flange c is first folded upon the flange c as seen in Fig. 3, and then doubled over behind the flange c as seen. in Fig. 4; this folding and doubling may be elfected as in the process known as seaming.

In the modified way of connecting the flanges which is illustrated in Fig. 5 the flangesz, c'- have each a return flange g, and

be desirable to finish the body pera l 508,840 L I instead of the joint between them being made by doubling the flange c'over the flange c as hereinbefore described, it is made by means of a hoop e which is-.put on hot over the flanges c c g g and then has its edges while still hot turned down into the grooves d dso that as the hoop shrinks in cooling it will draw the half barrelsb 11 together. Fig. 6 differs from Fig. in that the flanges c c are inturned instead of out-turned, the return flanges g g being dispensed with, and Fig. 7 is the same as Fig. 6 except that each -of the flangesc c hasa circular corrugation or indentationf, so, that the one corrugation or indentation fits into the other as seen in the figure and thus assists in making'the barrel liquidtight,and also gives additional strength. Although I preferably make the barrel or vessel in halves which aresubsequently secured together as before described I do not limit myself to actual halves, as it is evident that one of -the two parts mayform more than half and the other less than half of the barrel; each part, however, will consist of one head '01" end of the vessel and part of the body. Again for larger barrels it may be more convenient-to make each half or part in twozpieces or sections as shown in Fig. 8, one

less comprising the head or end a and part ot the body, and the other piece 11' being part of the body. .All the parts or pieces will be flanged and connected together in the manner already described.

For the purpose of strengthening the barrel body it may be corrugated either longitudinally orcircumferentially. Circumferential corrugations can be conveniently produced in the trimming machine; longitudinal 1. In a metal barrel,or other similar vessel, 4

a body consisting of two substantially hollow 5o tubular circular parts each having an annular inwardly extending recess in its outer surface and an annular lateral flange beyond said recess, andahutting against and connected to the like flange of the other part,

said flanges being of less projection than the depth of said recesses, whereby the joint between said parts is within their outer surface, substantially as and'for the purpose set forth.

. 2. In a metal barrel or other similar vessel, a body consisting of two substantially circular hollow tubular-parts b b, one of said parts having a laterally extending annular flange c at its end having an outer abutting face,

and the other of said parts having a like laterally extending annular flange c at its end of greater width than said flange c, and having a like outer abutting face, the said faces of said flanges abutting against each other, and said flange c embracing both sides of said flange 0', whereby said parts are connected together, substantially as and for the purposes set forth.

. 3. In a metal barrel'or other similar vessel, a body consisting of two substantially circular hollow tubular parts I) I) each having an annular peripheral recess d near its end, one of said parts having a laterally extending annnlar flange c' at its end having an outer abutting face and (if less projection than the depth of the recess d of such part, and the other of said partshaving a like laterally extending annular flange c at its end of greater width than said flange c and having a like outer abutting face, the said faces of said ,85

flanges abutting against each other. and said flange c embracing both sides of said flange 0', whereby said parts areconnected together, and the joint between said parts is within their outer peripheries, substantially as and for the purposes set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses. I
